In opinion of mine, the most important business functions which marketing can assist are:
- Finance/Management: marketing plans should include financial information for both new and existing products. In this sense, marketing can be a means supporting management when taking investment decisions. Marketing can also give inputs on sales forecasts under different marketing strategies scenario (Wind, 1981). Management can be supported by financial inputs provided by marketing but also to other data such as market actual (or expected) response to a product/service
